My biggest question is will you be unable to play this unless you have 2/3/4 *different* minions dead at the threshold you're at? For example, you cannot even cast Eternal Servitude from your hand if you haven't had a friendly minion die yet. If I've had 3x Obsidian Destroyer die and nothing else, is this just a dead card in your hand or will it just serve as a more expensive Eternal Servitude? Part of me suspects it's the former, because it's more likely the discover mechanic that prevents the casting of servitude with no dead friendlies, but in some ways upgrading would almost be a bad thing if it works similarly.

EDIT: Now I'm thinking it will not be castable if you don't have have X number of *different* dead friendlies because the Rogue spellstone says "Kill *up to* X random enemy minions."

Seems like the majority of people think this can only be used in Big Priest (which I see happening the most), but what about an OTK Priest build?

Priest would essentially run 4 minions, those being Barnes, Radiant Elemental, Phophet Velen, and Malygos or replacing Barnes with Y'Sharraj. The rest of the deck would be spells consisting of board clears and the rest of the combo pieces for the OTK. Essentially, you play the Spellstone and get Radiant Elemental, Velen, and Malygos all for 7 mana, and then can play two Mindblasts each for 20 damage and two Holy Smites each for 18 totalling a massive 76 damage in one turn for 9 mana. Might be useful with some of the new armor buffs classes are getting. Any thoughts on this or is this just too unrealistic and crazy to even attempt?

i think it cant work man. u cant survive only with spells. for example. u could need tanlos and a lot of other minions to draw the combo, like Loot Hoarder and other like it. so if u get it when u cast your 7 mana spell, and no velen or malygos come out, u are fuckd. Don't u agree?

They don't have to die. If they are still on board there is no problem, the ressurection is not necessary. Why the hell should you kill off your own Maly?? But you are right - transformation kills your whole combo.

So this card screams Big Priest. And probably this is the only place we will see it being played. I think that by turn 7, Big Priest should already have 3 minions dead, and it's fair to say that between early removal, Eternal Servitude and Shadow Essence there is a good chance that you have already cast 4 spells. And if you can Ressurect 3 minons, even if 1 of them is Barnes, you are off to a very easy late game.

Have you only ever played big priest ? If you don't get barnes early which is more than 60 percent of the time, your first minion is at best turn 6 so no, you most generally don't have 3 minions dead by turn 7.

Well I don't know if the chance is that low. If that's the case then it's not a good chance it's an ok chance. But the card will still be a 2 of because even as a 7 mana resurect 2, if those two are 9-cost cards you get some pretty good value.

I don't know why you're getting down votes. What you said is completely accurate. I've been playing big priest almost exclusively to combat the Keleseth Warlocks and Rogues that seem to dominate ladder and it's very few games I've done anything other than play board clears or spot removal by turn 7. Obviously, Barnes and Shadow Essence are what you're trying to get to "early" (well, early for BP standards) but really the goal is to just not die until you can just roll out massive roadblocks for opponent that they cannot deal with.

I would say unless you're counting minions you steal and trade with Potion of Madness it's VERY rare to have more than 2 minions dead by turn 7 and I'd say it's even uncommon to have ANY minions die before turn 7.

Very, very long-winded but still has insane power in big priest. Actually I think that that card is like made especially for this archetype. It seems blizza decided to make an upgrade for each of priest archetype's, which isn't a bad idea imo
